TSB vs Recall: What a Technical Service Bulletin Means for You

A recall is a mandatory, free fix for a safety defect; a technical service bulletin, or TSB, is the automaker’s instructions to dealers for repairing a known problem, and you pay for it unless a warranty or special program covers it. This guide explains the difference, the federal rule that makes TSBs public, when a TSB repair is free, and how to find the bulletins for your car.

The short answer: TSB vs. recall

Both start the same way: the automaker sees a pattern of problems in a model. What happens next depends on whether the problem is a safety risk. If it is, or if the vehicle doesn’t meet a Federal Motor Vehicle Safety Standard, the manufacturer must file a recall with NHTSA, notify every owner and fix it free. If it isn’t a safety issue, say a noisy transmission, a rattle, a software glitch or a warning light that comes on wrongly, the automaker usually issues a TSB telling technicians how to diagnose and repair it.

A TSB is not a sign that your car is unsafe, and it isn’t an instruction to bring the car in. It applies when your car shows the symptom it describes. A recall applies whether or not you’ve noticed anything, because the risk is there either way. Our recall guide covers how recalls work and the 15-year limit on free recall repairs.

What a technical service bulletin is

A TSB is a document an automaker sends to its dealers. It typically names the affected models and build dates, describes the symptom (“customers may report a shudder at light acceleration”), explains the cause and gives a repair procedure: reprogram a module, replace a part with a revised one, or adjust a component. Some bulletins are simply diagnostic tips, and a popular model can collect dozens over its life.

Although TSBs are written for technicians, they are not secret from the government. A federal regulation requires automakers to share them:

“Each manufacturer shall furnish to NHTSA’s Early Warning Division … a copy of all notices, bulletins, and other communications … regarding any defect in its vehicles or items of equipment … whether or not such defect is safety-related.”49 CFR 579.5(a)

The same rule covers warranty and policy extensions, product improvement bulletins and customer satisfaction campaigns, and automakers must file copies within five working days after the end of the month they are issued. NHTSA publishes them as “manufacturer communications,” which is how you can read them.

Recall, TSB, warranty extension and customer satisfaction program

Automakers use four kinds of fix programs, and owners often confuse them. The difference decides whether you’re notified and who pays.

The practical difference: NHTSA’s VIN lookup shows open safety recalls only. Warranty extensions and customer satisfaction programs appear on the automaker’s own owner site or at the dealer, so check both.

Will the dealer fix a TSB for free?

Only in these cases:

• You’re within the warranty that covers that part. A TSB repair on a car still under its basic or powertrain warranty is normally a warranty repair, at no charge.
• The automaker has a warranty extension or special program for the problem. These often cover one part, such as a transmission, a head gasket or an infotainment unit, for a longer time or mileage than the original warranty.
• The automaker agrees to goodwill. Out of warranty, an automaker may pay all or part of a TSB repair, especially if the car is close to the warranty limit and has a dealer service history. Ask the dealer to request it.

Otherwise you pay for a TSB repair like any other. The bulletin still helps you: it tells the technician what’s wrong and how to fix it, which can save diagnosis time, and it is evidence the problem is known if you later ask for goodwill or file a complaint. Bring the bulletin number to the appointment.

“Secret warranties” and the California law

When an automaker quietly pays for a known problem for customers who complain, but doesn’t tell other owners, consumer advocates call it a “secret warranty.” California regulates these programs directly. Its law defines an “adjustment program” as any program that extends a warranty or pays for repairing “any condition that may substantially affect vehicle durability, reliability, or performance,” other than safety or emissions recalls (Cal. Civ. Code 1795.90).

Under California’s rules, an automaker that adopts such a program must notify eligible owners by first-class mail within 90 days, tell its dealers within 30 days, and reimburse owners who paid for the repair before they learned of the program. Owners have two years from the date of payment to claim, and the automaker must answer within 21 business days (Cal. Civ. Code 1795.92). If you live elsewhere, your state attorney general’s consumer office can tell you whether a similar rule applies.

How to look up TSBs for your car

1. Search NHTSA. Go to nhtsa.gov/recalls, search by year, make and model, and open the manufacturer communications section of the results. You can read the bulletins free.
2. Ask the dealer. A dealer can run your VIN against the automaker’s bulletin system and tell you which TSBs and programs apply to your car specifically.
3. Check the automaker’s owner site for warranty extensions and customer satisfaction programs tied to your VIN.
4. Check owner complaints. If many owners report your symptom, a bulletin or program often follows. Open your model-year report from the VIN decoder to see complaints counted by component, or read our most common car problems analysis.

When a TSB turns into a recall

Some problems start as a TSB and become a recall once the automaker or NHTSA concludes they’re a safety risk, for example when a drivability issue turns out to cause stalling at speed. Owner complaints are a big part of that process: NHTSA reviews them alongside the bulletins automakers file, and a pattern can lead to an investigation and then a recall. If you experience a problem that feels like a safety issue, report it; our guide explains how to file a complaint with NHTSA.

If you paid for a repair that later becomes a recall, ask for your money back: federal law requires recall remedy programs to include a plan for reimbursing owners who paid for the repair a reasonable time before the recall. Keep every repair invoice.
